Today i decide to make this thread for explain some things with the ClientState.

First , i know some guys have found this also , but their information are not correct.

I'll Give you some exemple about this , and these informations it's the same for all cod's.

-> Modern Warfare 3 ClientState : 0x0110A280

Are you sure about this offset ?:

- Yea , Look this :

So , at this offset , you can get / set some informations for all clients in game, When you leave your party , all bytes are Refreshed/Reset.

This function work also with the g_client , his size for Mw3 is 0x3980 :

You can also easily found it in debugger , exemple you need just to do math. Find your name in game for change it , and find the name of your friend also. Once you have this , done this math (example) :

Name in game Client 0 : 0x0110D694
Name in game Client 1 : 0x1111014

So :

0x1111014 - 0x0110D694 = 0x3980

You have now understand how to do , i'll give an exemple with C# language for give easily your bytes for clients :

You can now send easily mods to your friend , you need just to do maths , don't forget for the client 16 it's 0x10 & the client 17 it's 0x11.

With the ClientState you could change weapons , change the state for mFlags , Names Clients...

I Saw also someone who has leak the God Mode. The God Mode is just the health of players in game , but it's not with ClientState, He is in the g_entity.

-> Modern Warfare 3 g_entity : 0x00FCA280

- It's like the ClientState but he is different , he do others things and his size for client is different.
- You can check in the XREF from the clientState his location :

The Size for give something to a client is 0x280

You have just to change my example C# with the right offset for this and it's the same thing

Faster exemple : 0x00FCA280 + (ClientIndex * 0x280) + 0x19f

0x19f is the location to the health to players. Original bytes is 0x64 (0x64 in Decimal it's 100)

You can also put 0xFF ahead , so put this offset 0x19e.

I'll not explain everything about these functions , it's now to you to find others things yourself. It's not necessary to release once you have found other things keep this for you and like that everyone will found themselves.

I hope these information will help you with the modding, if i may have said one or two errors in this thread , tell me i'll edit it.
